Use my Orbi RBK50 as single point of connection?

No.  There is one specific model of Orbi that contains a DOCSIS 3.0 modem and can be connected directly to the cable feed.  All the other models require an internet modem.

Modem Combo Units:
This would be a double NAT condition which isn't recommended. https://kb.netgear.com/30186/What-is-Double-NAT

Couple of options,
1. Configure the modem for transparent bridge or modem only mode. Then use the Orbi router in router mode. You'll need to contact the ISP for help and information in regards to the modem being bridged correctly.
2. If you can't bridge the modem, disable ALL wifi radios on the modem, configure the modems DMZ/ExposedHost or IP Pass-Through for the IP address the Orbi router gets from the modem. Then you can use the Orbi router in Router mode.
3. Or disable all wifi radios on the modem and connect the Orbi router to the modem, configure AP mode on the Orbi router. https://kb.netgear.com/31218/How-do-I-configure-my-Orbi-router-to-act-as-an-access-point and https://www.youtube.com/watch?v=H7LOcJ8GdDo&app=desktop

Hi, appreciate your advice.

 

I have installed and connected my Orbi RBR50 to my internet providers modem/router however I am experiencing some conflict (connection is not always stable) between the two.

So, can I get rid of my internet services modem/router and simply use my Orbi RBR50, only. 

 

Many thanks,

Sean
